The double stroke roll is a rudiment consisting of alternating diddles (i.e., RR, LL, etc.) of indeterminate speed and length. There are 10 official variants of the double-stroke roll (see below).

No.	Name	Notation	Description
6.	Double Stroke Open Roll		Like the single-stroke roll, usually played fast, but even when played slowly, alternating diddles are considered a double stroke roll. Played so each individual note can be heard distinctly.
7.	Five Stroke Roll		Two diddles followed by an accented note.
8.	Six Stroke Roll		Unlike most other double stroke rudiments, the six stroke roll begins with an accented single note. Then it is followed by the diddles and another accented note.
